Image Processing Preview Region Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image processing systems, users face difficulties in efficiently searching for the appropriate preview images among numerous combinations of attribute values for reading attributes, making it hard to set the correct attribute values for generating read images of original documents.
Innovation Solution
An image processing system that displays a list of reading attributes, specifies a preview region on the original document for generating preview images, and allows users to select attribute values through an attribute value selection screen, enabling efficient setting of attribute values by associating each attribute value with a preview image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple preview images are generated by combining attribute values of reading attributes, then the user can check the appropriateness of setting values, but the number of preview images increases making it difficult to efficiently search for the intended attribute value
Solution Approach 1:
The patent segments the attribute selection process by separating the selection of one reading attribute from others. When a user selects one reading attribute, the system generates preview images only for that specific attribute's different attribute values, rather than generating all possible combinations of multiple attributes. This segmentation reduces the number of preview images from exponential combinations to a manageable set for a single attribute.
Solution Approach 2:
The patent changes the dimension of presentation by displaying multiple preview images corresponding to different attribute values of the same reading attribute in a structured layout. This allows the user to visually compare the effects of different attribute values (e.g., different resolutions or color modes) on the same preview region, making it easier to select the appropriate value without being overwhelmed by combinatorial complexity.
2Loss of information
If all combinations of reading attribute values are processed, then complete preview coverage is achieved, but the processing time and computational resources increase
Solution Approach 1:
The patent extracts and focuses on one reading attribute at a time for preview image generation. Instead of processing all combinations of multiple reading attributes simultaneously, the system extracts the currently selected attribute and generates previews only for its different attribute values. This extraction approach maintains sufficient preview coverage for the selected attribute while significantly reducing processing time and computational resources.
3Loss of information
If the system displays all preview images for all attribute combinations, then the user has complete information for selection, but the user interface becomes complex and difficult to navigate
Solution Approach 1:
The user interface is segmented to display preview images for one reading attribute at a time. When a user selects a reading attribute from a list, the system presents a focused view showing only the preview images relevant to that attribute's different values. This segmentation simplifies the interface by eliminating the need to navigate through all possible attribute combinations, making it easier for users to find and select the appropriate attribute value.

AI summary
An image processing system includes an imaging unit, and a processor, in which the processor is configured to display a list of reading attributes set in a case where a read image of an original document is generated in response to a user operation, specify, as a preview region, a partial region on the original document that is a generation range of a preview image of the original document in a case where one reading attribute is selected from the list of reading attributes by a user, generate the preview image corresponding to the preview region for each attribute value obtainable for the one reading attribute from a captured image of the original document captured by the imaging unit, display an attribute value selection screen showing an association between each attribute value obtainable for the one reading attribute and the preview image generated in accordance with the attribute value, and set an attribute value selected from the attribute value selection screen by the user as an attribute value of the one reading attribute in a case where the read image of the original document is generated.
